College Football Picks: Can OU avoid Big 12 champ upset?

There was a time when the Big 12 championship game was routinely a dream-wrecker for national title contenders.

From the first Big 12 title game in 1996 to 2010, the last before it took a hiatus while the conference realigned, the league's championship was won by the lower-ranked team five times. There was also a memorable near-upset.

No. 9 Texas tries to become the latest Big 12 team to spoil the conference's chances at a national championship Saturday when it faces No. 5 Oklahoma in Arlington, Texas. The Longhorns beat the Sooners in the regular season on a last-second field goal.

The very first Big 12 championship game set the tone for chaos to come: No. 3 Nebraska was upset 37-27 by unranked Texas. Two years later Texas A&M knocked off No. 2 Kansas State, keeping the Wildcats out of the very first BCS championship game. In 2003, Kansas State threw the BCS for a loop, blowing out No. 1 Oklahoma 35-7. The Sooners still made the championship game.

Missouri was No. 1 in the country in the unpredictable 2007 season when it was beaten by Oklahoma in the Big 12 title game. Texas nearly had a BCS championship game appearance slip away in 2009 when it beat Nebraska 13-12, a game remembered most for Ndamukong Suh's dominant performance for the Cornhuskers.

The return of the Big 12 title game came with a new format. The 10-team conference no longer has divisions, but matches Nos. 1 and 2 in the standings. And because the Big 12 plays a round-robin, nine-game conference schedule, the championship game will always be a rematch. Conference leadership believed it needed an extra quality game to best position its champ for playoff selection and the risks outweighed the reward.

Oklahoma beat TCU to make the playoff last season. We'll see if Big 12 volatility makes an appearance with the Sooners in prime position to make it again, sitting at fifth in the playoff rankings, behind Georgia, which plays top-ranked Alabama in the Southeastern Conference championship.
